Answer:
The concentration equilibrium constant is
Explanation:
The chemical equation for this decomposition of ammonia is
↔
The initial concentration of ammonia is mathematically represented a
The initial concentration of nitrogen gas is mathematically represented a
So looking at the equation
Initially (Before reaction)
During reaction(this is gotten from the reaction equation )
(this implies that it losses two moles of concentration )
(this implies that it gains 1 moles)
(this implies that it gains 3 moles)
Note : x denotes concentration
At equilibrium
Now since
Now the equilibrium constant is
substituting values
Answer:
<h2>The answer is 4 m/s²</h2>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
where
a is the acceleration
f is the force
m is the mass
From the question
f = 20 N
m = 5 kg
We have
We have the final answer as
<h3>4 m/s²</h3>Hope this helps you
